Allow him to re-introduce himself: JAY Z's discography is officially back on Spotify in honor of the rapper's 50th birthday, and Spotify confirms it's for real this time. This includes classic albums like Reasonable Doubt, The Blueprint, The Black Album, and Vols. 1, 2 & 3, his recent comeback album 4:44, and even the albums you probably don't need to hear anyway, like Kingdom Come. Obviously there were plenty of other ways to hear these albums over the past few years, but for Spotify-using JAY Z fans, this is an exciting day. Listen to them all here and stream a few highlights below.

Earlier this year, Beyonce -- who is one of Spotify's most streamed artists of the decade -- finally put Lemonade on Spotify (and Apple Music) for the first time.
